A contractor quoting a heat pump install in Lyman County has to get the sizing right before anything else on the spec sheet matters. Homes in Lyman County, SD run heat about eight months a year, from October through May. Heat pumps lose heating capacity as outdoor air cools, so a unit that tests fine in mild weather falls short on the coldest days of a long South Dakota winter. An undersized system runs the backup resistance heat far more than intended, and that shows up on the electric bill before it shows up as a fault code. The load calculation, and the choice of balance point, are where a good install earns its keep.
Ductwork and electrical service are what decide how a heat pump installation actually goes, and in much of Lyman County's housing stock both were put in for systems that drew far less than a heat pump draws today. Half the homes in Lyman County, South Dakota were built in 1976 or earlier (2020-2024 ACS 5-year). That gap between what the wiring was sized for and what a new unit pulls means the panel gets evaluated before the equipment gets quoted. A contractor who skips that step will misprice the job.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. The indoor air handler mounts inside, usually in a utility space, basement, or closet, and moves conditioned air through the home. These two units are the core of what a contractor brings to the job.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through insulated copper tubing that passes through the exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the system. The condensate drain line runs from the air handler to a floor drain or outside, removing the moisture the indoor coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly which components and configurations apply to your house.
